SPARK-PLUG CONNECTOR.

Specification of Letters Patent.

Patented Sept. 21, 1915.

To all whom it may concern Be it known that I, ARTHUR H. 0011s, a citizen of the UnitedStates, residing in the city of Louisville, county of Jefferson, and State of Kentucky, have invented a certain new and useful Improvement in Spark-Plug Connectors, of which the following is a specification. v

This invention relates to spark plug connectors, and is intended particularly for use in connection'with automobiles though it may be found of service in other places where a ready means of securing'and releasing a circuit wire is desired.

An object of the invention is to provide a connector which will obviate the use of screws and nuts in the securing of a wire.

Another object is the provision of a conmotor which may be readily and firmly secured to a circuit wire and when so secured may easily be attached, with one hand to a spark plug, or other device.

.VVith the foregoing and other objects in view my invention consists of the novel construction and arrangement of parts illustrated in the accompanying drawing, wherein is set forth an embodiment of the invention, but it'is to be understood that such modifications and changes may be resorted to as come within scope of the. appended claim.

Referring to the drawing wherein like reference characters designate like parts, Figure 1, is a side elevation of an embodiment of my connector in position on a spark plug. a Fig. 2, is a perspective of the connector; Fig. 3, a perspective of the inner, or sliding member; Fig. 4., a perspective of the outer member; Fig. 5, a plan of the inner member; Fig. 6, a bottom plan of the outer member; Fig. 7, a diagram of the blank from which the outer member is formed; Fig. 8, a diagram of the blank from which the inner member is formed; Fig. 9, a perspective of the inner member.

Referring tothe drawing 1 designates .a spark plug of usual construction having a terminal projection 2-to whichmyimproved connector 3 is affixed, the connector being secured on the end of a high tension electrical conductor 4., such as is employed in automobile use, comprising a metallic wire, or strand, 5- surrounded by an insulating sheath 6.

The connector 3 comprises apair of suitably shaped, preferably rectangular, hollow members 7 and 8, the member 7 being adapted to slide within the other member.

A pin 9 which passes through diametrically opposed openings 10 10 po sitioned respectively in the upper and lower wallsof the outer member and through corresponding slots 11 and 11 in the inner member serve to retain the two members in operative relationship while permitting relative recipr'ocatory movement thereof. The inner member is divided by a longitudinal partition forming a compartment 13 within which is positioned an expansible coiled spring -1-1- which serves to keep the inner member at the outer limit of its movement. The inner member is provided with diametrically opposed perforations 15, 15, in the upper and lower walls thereof, adapted, when the member is at the inner limit of its movement, to register with corresponding perforations 16, -l6 in the outer member. The bottom 17 of the outer member is extended rearwardly forming a tongue -18 having a plurality of perforations 19- through which the bare wire 5 may be passed and secured. The tongue 8 has laterally extended ears .20- which are adapted to be clamped around the sheath 6, securing the connector rigidly thereto.

In using the connector it is taken between the thumb and second finger, pressure exerted, with the forefinger, on the outer end of the inner member forcing it inward as far as it will go, the connector-is then positioned on the spark plug, with the terminal projection 2 extending through the alined perforations 15-, 15 and 16, 16", pressure on the inner member is then removed and the spring 14 forces the same outward, causing the opposing edges of the perforations to bind on the terminal 2, making electrical contact therewith and holding the connector firmly thereon.

Having thus described my invention so that anyone skilled in theart pertaining thereto may make and use the same, I claim:

A connector comprising a hollow outer member open at one end and having a'plu rality of diametricallyv opposed perforations in its upper and lower walls, a second member adapted to slide therein and open at its inner end, said inner member having a pair of diametrically opposed slots adapted to register with certain of said perforations, a pin passing through said registering slots and perforations and adapted to hold said members in operative relationship while permitting relative longitudinal movement thereof, said inner member having apair of diametrically opposed perforations adapted to register with others of said first named perforations only when the members are in a given position, said inner member having a longitudinal compartment, an expansible l0 springpositioned Within said compartment said members,' and. a tongue extended from 'the rear .ofthe outer member having means for the: attachment thereto of an electrical condilctor.
